50+ Chain Guards (eek!!)

OK, I am seriously thinking about getting a chain guard for my "hop on and do chores" mtn bike (Spec HR) now used mostly for utility and chores.

ANyone here use a chain guard?

Do they actually still make chain guards?

Would a chain guard fit over a triple front DR?

The problem - I frequently hop on the bike - even while wearing levis or other long pants - to runb to the store or take a quick ride, etc. Of course, I never have time for a rubber band, and I lose those little velcro thingies for your pants legs.

Assuming you don't use it very much, how about replacing the big chainring with a bash guard? I'm thinking that would help keep your pants cuff out of the chain and could be easily done with off the shelf hardware.
